Mirror neurons are a specific kind of visuomotor neurons that are involved in action execution and also in action perception. The mirror mechanism is linked to a variety of complex psychological functions such as social-cognitive functions and language. People with schizophrenia have often difficulties both in mirror neuron system and in language skills. In the first part of our research we studied the connectivity of mirror neuron areas (such as IFG, STG, PMC, SMC and so on) by fMRI in resting state and the differences between a group of patients during first episode psychosis and a group of healthy controls. The second part of our research was dedicated to language: if there are specific activations in certain parts of the cortex (such as SMC, Broca's and Wernicke's areas) along with a specific meaning of the word stimuli and if these activations are disrupted in patients with schizophrenia. The first part of the research showed a significant difference in the mirror neuron system connectivity between these two groups. The patients had stronger connections between the thalamus (which mediates sensory information) and the cortical areas while the controls had the cortical areas more interconnected. The second part of our research, a language experiment, showed significant differences between the...

Gekrümmte Röntgen-Multilagen-Spiegel fokussieren Synchrotron-Strahlung auf wenige zehn Nanometer große Strahlflecke. Die Propagation zweier Lichtwellen durch elliptisch geformte fokussierende Multilagen-Spiegel wird durch eine wellenoptische Theorie beschrieben; dieser analytische Ansatz wird numerisch integriert. Mit diesem Verfahren kann die Schichtstruktur für hohe Reflektivität und geringe Strahl-Aberrationen optimiert werden. Wir zeigen Simulationen aktueller und neu entwickelter Synchrotron-Strahlrohre. Die Grenzen der Theorie werden anhand von Modell-Parametern untersucht.Ein weiterer Teil dieser Arbeit beschäftigt sich mit partieller räumlicher Kohärenz, modelliert mit der Methode der stochastischen Superpositionen. Propagation und Filterung der Kohärenzeigenschaften eines Röntgenstrahls in einem Wellenleiter werden analytisch und numerisch untersucht. Das vorgestellte, anschauliche Modell soll die Entwicklung und Überprüfung neuer Algorithmen im Bereich der kohärenten Abbildung unterstützen. Wir vergleichen die Ergebnisse von Simulationen, die auch Realstruktureffekte berücksichtigen, mit experimentellen daten aus dem GINIX-Instrument am Kohärenz-Strahlrohr P10 an der PETRA III-Quelle am DESY.Diese Arbeit zeigt Ergebnisse aus einer Kollaboration zwischen der Georg-August-Universität Göttingen und der European Synchrotron Radiation Facility (ESRF) in Grenoble.

Mirror neurons are very specific nerve cells that are both motor and sensory in nature. Mirror neurons are a relatively new discovery first identified by a team of neurophysiologists at the University of Parma. These neurons were first observed in primates, and then later in humans in several regions of the cerebral cortex. A large amount of research on mirror neurons have shown that they play an important role in imitation, language acquisition and empathy. The theoretical part of this work summarizes what is currently known about mirror neurons. It emphasizes the relationship between mirror neurons, autism, empathy, and its training. This theoretical framework is followed by pilot research, which consists of two components: the quantitative part consisted of a questionnaire survey to ascertain the level of empathy of the participants using the Index of Interpersonal Reactivity. The participants were the parents of autistic children who were compared with a control group. A statistically significant difference in empathy levels between the two groups was not observed but there was a tendency for higher scoring in some questionnaire scales in experimental group The second part of this work is an analysis of observations of the interactions between parents and autistic children. Additionally, two...

Silicon-on-insulator (SOI) technology has become increasingly attractive because of the strong light confinement, which significantly reduces the footprint of the photonic components, and the possibility of monolithically integrating advanced photonic waveguide circuits with complex electronic circuits, which may reduce the cost of photonic integrated circuits by mass production. This thesis is dedicated to numerical simulation and experimental performance measurement of passive SOI waveguide devices. The thesis consists of two main parts. In the first part, SOI curved waveguide and corner turning mirror are studied. Propagation losses of the SOI waveguide devices are accurately measured using a Fabry-Perot interference method. Our measurements verify that the SOI corner turning mirror structures can not only significantly reduce the footprint size, but also reduce the access loss by replacing the curved sections in any SOI planar lightwave circuit systems. In the second part, an optical 90o hybrid based on 4 × 4 multimode interference (MMI) coupler is studied. Its quadrature phase behavior is verified by both numerical simulations and experimental measurements.

The final thesis is aimed at mirror comparison of mutual trade between the Czech Republic and Germany. On the basis of the comparison of Czech and German methodologies of foreign trade and consequential analysis of their mirror comparison focused especially on effect of the Czech Republic's accession to the EU (access effect) were individual abnormalities affecting mirror comparison identified and described. There were several solutions put forward so that already detected abnormalities could be effectively dissolved, moreover their figure in mirror comparison could be eliminated and data acquired from the comparison would reach as high level of credibility as possible. The Single flow and Qualified single flow systems are described and discussed in relation to mirror comparison because they are possible and already existing plans for simplification of Intrastat.

The EIT Raw Materials Project MireBooks intend to teach mining students by simulating a VR mine and recreating learning experiences in it. With this comes challenges with regards to the networking performance and user experience. / MiReBooks

Orientador: Gabriela Kvacek Betella / Resumo: A presente tese apresenta uma análise comparada entre signos escatológicos, ou seja, relativos à morte, presentes nos contos de Machado de Assis e nos episódios da série televisiva Black Mirror. Amparado pelos preceitos conceituais da Semiótica Interpretativa e pelo modelo metodológico enciclopédico-cognitivo de Umberto Eco, este trabalho apresenta, a princípio, uma discussão teórica realizando um recorte crítico sobre o autor brasileiro e sobre a tipologia das narrativas seriadas audiovisuais contemporâneas, a fim de respaldar o traquejo analítico empreendido. A proposta central desta pesquisa é confrontar processos de elaboração sígnica os quais envolvam questões tanatológicas em oito narrativas: Nosedive e O Espelho, White Bear e A Causa Secreta, San Junipero e A Segunda Vida, e Be Right Back e Um Esqueleto, do programa britânico e da literatura machadiana, respectivamente. Tal labor reflexivo reconhece a inserção dessas produções em um continuum sígnico, situando-as como expressões das mentalidades de seus tempos em vias escatológicas. Para concatenar tais percepções, esta tese forja o pensamento enciclopédico esboçado pelo semioticista italiano, lançando-se na escavação das representações da morte, do paraíso e as atitudes humanas diante do esgotamento da vida desde a Antiguidade Clássica até os dias atuais, por vieses históricos, culturais e sociais, permitindo que se crie um panorama-arcabouço acerca desses signos no decorrer dos tempos e suas ressonâncias. Por fim, a ...

Supported by the theoretical precepts of Umberto Eco's Interpretive Semiotics and encyclopedic-cognitive methodological model, this work introduces an academic discussion, making a critical cut about the brazilian author and the contemporary audiovisual serial narratives typology, to support the analytical approach undertaken. This research main purpose is to confront sign elaboration processes that involve tanatological questions at eight narratives: Nosedive and The Mirror, White Bear and The Secret Cause, San Junipero and The Second Life, and Be Right Back and A Skeleton, from the british program and Machado's literature, respectively. Such reflexive work recognizes the insertion of these productions in a signic continuum, situating them as expressions of their times mentalities in eschatological ways. To concatenate these perceptions, this thesis forges the encyclopedic thinking outlined by the Italian semioticist, launching into the excavation of death, paradise and human attitudes towards the exhaustion of life representations from classical antiquity to the present day, by historical biases, cultural and social aspects, allowing a framework to be created about these signs over time and their resonances. Finally, comparative analysis handles semiosis arranged in differen...
